The
new
technology
will
make
it
possible
to
transmit
more
than
10GW
up
to
3,000km,
according
to
the
Switzerland-based
power
and
automation
group,
which
says
it
has
successfully
tested
the
system.
That
would
surpass
the
6.4GW
capacity
of
the
world’s
first
commercial
800kV
UHVDC
connection,
China’s
Xiangjiaba-Shanghai
link,
which
was
commissioned
in
2010
by
ABB.
The
Xiangjiaba-Shanghai
connector
–
the
longest
of
its
type
–
transports
electricity
generated
at
the
Xiangjiaba
hydropower
plant,
located
in
the
southwest
of
the
country,
some
2,000km
to
Shanghai.
HVDC
technology
underpins
the
higher
voltage
levels
needed…
